Convert array types with Buffer.BlockCopy - Permalink
If you are searching a high performance way to convert a primitive type array into another, the BlockCopy method of the Buffer class can save the day:
As an example we will convert an int array into a byte array:
Code by NETMaster (Thomas Scheidegger)
public static void BlockCopy (
Array src,
int srcOffset,
Array dst,
int dstOffset,
int count
)
Array src,
int srcOffset,
Array dst,
int dstOffset,
int count
)
As an example we will convert an int array into a byte array:
int[] ai = new int[] { 0x11223344, 0x55667788 };
byte[] ab = new byte[ Buffer.ByteLength(ai) ];
Buffer.BlockCopy( ai, 0, ab, 0, ab.Length );
byte[] ab = new byte[ Buffer.ByteLength(ai) ];
Buffer.BlockCopy( ai, 0, ab, 0, ab.Length );
